A recent theoretical analysis of the temperature dependence of the magnetic response of neutral disorder-induced solitons 69], has revealed that these solitons may explain the low-temperature deviation from Curie behavior that is observed in experiments on Durham /ra/t.y-polyaeetylene [70]. A more stringent test of the theory would involve extending these experiments to even lower temperatures (down to 1 K or lower). 

Magnetically responsive gelatin microspheres, prepared using methods adopted from albumin preparations (161), were evaluated... 

Experimentally, temperature chaos can be evidenced by aging the system at a temperature T, and changing the temperamre to a T, + AT. If the temperamre shift is large enough, the equihbrium domain configurations at 7] and 7] + AT are completely different on the length scales relevant for the experiment. Hence, if the magnetic response at 7] + AT is the same as after a direct quench, the system appears rejuvenated.

Critical current measurements have been made with a variety of techniques. The indirect technique, that of obtaining the critical current from the magnetization response is discussed in Chapter 18. Direct transport measurements, using attached current and voltage leads, and indirect measurements requiring macroscopic current circulation will be discussed. Critical currents are desired as a function of both temperature and applied magnetic field since a variety of theories discuss the functional relationship. And applications may require either or both of these data. 

Since it is much more convenient to weigh a sample than to measure its volume accurately, the magnetic response is often expressed as the moment per unit mass, m/W, where W is the weight of the cylinder. The proportionality between the internal field and the moment per unit mass is termed the mass magnetic susceptibility xg with units of cm3/g. Obviously, xv and Xg are simply related by the density of the cylinder p = W/V ...

Angular momentum arguments show that the Jt-electron-rich nature of (4 +2) SN heterocycles is the key to their diatropic current. Formal expansion of (4 +2)-Jt-carbocyclic systems by insertion of NSN motifs in every CC bond is predicted to lead to structures that support diatropic ring currents explicit ab initio calculation of magnetic response predicts the 24-center, 30n-electron heterocycle S6N12(CH)6, formally derived from benzene, to be aromatic on the basis of this criterion <2002JA11202>. 

SCF and MSCF electric field dependence of the magnetizability and nuclear magnetic shielding have been studied by Rizzo et al (17-19) within GIAO basis sets. The use of London orbitals guarantees invariance of theoretical estimates in a change of coordinate system, which is a basic requirement in the computation of magnetic response properties. 

The next paragraph introduces briefly the set of magnetic parameters (MPs) that determine the spacing of the lowest energy levels in metal complexes. Then the magnetic response functions can be reconstructed using statistical thermodynamics.
